Application me afrui so,

To all whom. it may concern V Be it known that EDWIN E; THOMAS, citizen of the United States of Ainericmand resident of the city "of Portland, in the county of Multnomah, in the State-of Ore-, gen, has invented certain new and useful Improvements in LawnSprinklers, of which i the following is a specification,reference he- .ingjhad to the accompanying drawings.

My inventionrelates to lawnsprinllrlers, and has for its object the production of an automatically xvibratory nozzle-supporting device which is reliable of operation and which is simple, durable, andgeconomic of construction.

' hat constitutes iny. invention will be hereinafter specified in detail and succinctly set forth in the appended claims.

In the accompanying drawings:

Figure II is 'a rearfelevationof thefprimary supporting frame. r

Figure III fs atop planviewof a portion of the subject mattei' ,ofljignire I with the .hOSGQQlld nozzle omitted, showing in dotted linesoperative changesof position of the hosecarrier and adjiustment of one of .the striker-plates.

Figure IV "s a detail view; ,in sideelevation thereof, of the,nozzlefadj ustingholder. 1 F igure V is a detail view insideelevation as shown in Figure I and on slightly en'-' larged scale of the jet actuated hose-carrier shifting stud.

Figure V1 is an elevation of the same taken at. right angles thereto looking towards the primary supporting frame.

Referring to the numerals on theQdrawin'gs, 1 indicates apriinary supporting frame that islpreferably hi furcatedandmay be made of stiff wire bent to inversely UQshape, and having terminally sharpened {1egs2and- 3 adapted to be thrust endwise into the ground that is'findioated by 4 in Figures 1 and II;

f'The frame 1 preferably carries a crossbarfi'having apertured lugs 6, disposed in pairs, for the reception of the respective legs 2 and 8, and adjustable thereon asjby abutment screwsi'i'. The cross-bar5 is also preferably [provided midway between said 1919; Serial no. 314,232.

legs with a pin8i -'I o said'pinyas by -engagement' of a head 9--pr0vided with an elongated slot 110 for its receptiomis loosely secured; a hose-carrier-arm 11 e f any suitable length 1 preferred. It {is designed and adapted to support the otherwise free end of a hose 12 that terminates ina nozzle 15 of any usual or preferred form. Near" its free end, the arm "11 is preferably provided with aparted loop 16 that is preferably made of a generally rectangular shape well shown in Figure 1V. Sa id loop is preferably provided on three sides with abut-mentscrews 17, one for each of :saidsides', Whereby the nozzle 15 may be secured to the arm '11 and adjusted to desired disposition thereon. I

The arm 11 is pendulously supported upon the frame 1 as by-a'ehain 19 or-other flexible 1ne1nber secured atone end, as at 20 to the carrier and-whose-loose end may be secured in lengths determinable at will, asby a pin 21 preferably located on the top bend or arch of the frame 1 adapted toengage any open link or other aperture therein, as. indicated in Figure I.

Substantially at the free end of the arm 11, is suitably mounted an oscillatory hosecarrier shifting-stud 22 having two -p referably plain faces 23 and 24 which are preferably of wedge-shaped relative disposition, as best-shown in Figured-I I; The stud 22,

havingthe said preferably convergent faces 23 and 24, is actuated about its oscillatory axis "by a Water-jet discharged in service fromgthe nozzle 15' against said faces a1- ternately. When s'ucha jet'strikes'the edge f-the wedge -forined'by-the faces 23 and 2 t,

it issplit bythewedge, but as often as it hits one face orthe other with a preponderating "force," it converts the 'sidethat'iis hitinto a vane and causes-the stud 22 to turn upon its axis. In order operatively to utiilize the action'last naincdof saidstud, Iprefer tozprovide ,upon the stud anarin 25 projecting therefrom radially ,to its pivotal axis and'to that armby a loosepivotal-connection 26 uni'te one end of a rod 27, whose other end is in like manner connected to a bell crank flever 80, pivotally secured as indicated at 31,-to'the arm 11. InJFigure-II -I it .willbe noted that the'rod 2,7 is arranged in I close proximity :to theedgegof the hose can rying arm '11, and alsojto theloop 16, so that the .rod, if. moved far enough, will abut the 33 and 34.

loop 16 at times to limit the swinging movement of the lever 30 in both directions, and likewise the oscillating movement of the stud 22. The free end of the lever 30 carries a cross-head 32 whose ends are arcuated as shown, as the arm 11 is swung from side to side, strike alternately against strikerplates 33 and 34 carried by the frame 1 preferably upon the cross-bar 5. The connec tion between the said respective plates is preferably an adjustable one, obtained, for example, by wing nuts 37 threaded each to a stud-bolt extending through an aperture provided for its reception in a fin-bar 38 projecting from its respective striker-plate.

The distance between the plates 33 and 31, obtained by their relative adjustment on the cross-bar 5, determines the operative swing of the arm 11.

It is to be particularly noted that the pivot point 31 of lever 30 is situated beyond or forwardly of the forward edges of the strikervplates 33 and 31-, whereby the lever 30 will always be swung toward the arm ll when the arcuated ends of the cross head 32 engage and slide upon the plates In other words, thepivot 31 should be so situated with respect to the striker plates 33 and 3 1, that radial lines from the pivot 31 to the initial points of contact of the arcuate ends of crosshead 32 with the plates 33 and 34, define with said plates, angles of more than This arrangement is resorted to in order to prevent the crosshcad 32 swinging to parallel the striker plates 33 and 34. The operation of my device may be briefly described as follows: V

The frame 1, having been planted in the ground in the location selected, the nozzle 15 is, by the aid of the abutment screws 17, secured and properly centered within the loop 16 upon the arm 11. The angle of inclination of said arm with respect to the frame is then determined and fixed by the attachment to the pin 21 of the chain 19, the cross-bar 5 with its appurtenant strikerplates 33 and 34 being correspondingly adjusted and fixed upon the frame 1.

A jet issuing from the nozzle 15 will hit the stud 22 as it finds it. To function prop- .erly it must strike one of the stud faces 23 until the crosshead 32 impinges against that one of the striker-plates 33 or 34; which is disposed 1n the path of its movement. Thereupon, in consequence of said impingement, the lever 30 is caused to turn upon its pivot 31, thereby imparting through the rod 27 and radial arm 25 an oscillation to the stud 22, with the effect of presenting to impingement of the nozzle jet a change from a face 23 or 2 f, as the case may be, to the other of said faces. As soon as said change of faces takes place, the movement of the arm 11 is reversed and continues as above described until it in turn is reversed. The movement of the arm 11 in alternating di rectiens continues automatically as long a jet of sufficient force to operate it issues from the nozzle 15. It may be necessary to initiate, by manipulation, vibration of the arm 11, but after it is once set in motion no further attention is ordinarily required in order to effect its continued operation.
